Section activities focus on these products:
- Low-voltage power, control and communications systems.
- For surge suppression on circuits rated 1000v (RMS) ac and below.
- For surge suppression on circuits rated 1500 dc and below.
- These devices include components, modules, assemblies, or hybrid circuits comprised of active or passive elements (linear or non-linear) or any combination of these elements, packaged to divert, clamp, filter or in any other way limit surge voltages.
Standards play a vital part in the design, production, and distribution of products destined for both national and international commerce. Sound technical standards benefit the user, as well as the manufacturer, by improving safety, bringing about economies in product, eliminating misunderstandings between manufacturer and purchaser, and assisting the purchaser in selecting and obtaining the proper product for his particular need.
NEMA devotes much of its time, effort, and resources to voluntary standardization activities. NEMA standards are offered and recommended to become American National Standards under the procedures of the American National Standards Institute. This decision rests with the particular subdivision or subdivisions concerned. It is the intent of the association to continue its support of these, and many more, activities as the best method to continue providing sound and safe electrical products for the use of all.
Relevant Standards and Publications:
Standards and publications relevant to the Low Voltage Surge Protective Devices Section include:
Key technical activities include:
· Publication and maintenance of relevant NEMA standards.
· Maintaining active liaison relationship with UL, and participate in the maintenance activity for UL Standard 1449, Transient Voltage Surge Suppressors.
· Maintaining active involvement in the National Electrical Code® revision process.
· Funding the TAG Administrator function for USNC involvement in IEC/SC 37A, Low-voltage surge protective devices; and IEC/SC 37B, Specific components for surge arresters and surge protective devices
International Electrotechnical Commission (IEC)
· The Low Voltage Surge Protective Devices Section is involved in IEC activities. Subcommittee 37A, Low-voltage surge protective devices, is responsible for international standards for low voltage surge protective devices (SPDs) and for information on their selection and application.
· Subcommittee 37B, Specific components for surge arresters and surge protective devices, is responsible for international standards for components used in SPDs. These SPDs are used in power, telecommunication and/or signaling networks with voltages up to 1000 V a.c. and 1500 V d.c. Currently, the United States National Committee (USNC) to the IEC holds the Secretariat for SC 37B. The Section sponsors the funding of NEMA staff to fulfill the Secretarial responsibilities.
· The United States National Committee (USNC) is represented on SC 37A and SC 37B and NEMA members provide expert representation on multiple project teams.
· NEMA holds the function of Administrator for the USNC Technical Advisory Group (TAG) to SC 37A and SC 37B. These TAGs are the mechanism for establishing U.S. positions on the committees’ standardization actions.

Through NEMA, the section develops industry positions on legislative and regulatory initiatives that may affect member products, markets, and customers. NEMA's work has resulted in contributions to public policy development and in promoting competitiveness, technological progress, and public safety. On the Government Affairs homepage members can search for and e-mail federal representatives to convey opinions regarding energy policy or other issues related to the electroindustry.
NEMA Government Affairs provides specific services to its members and information in the areas of Environment, Health & Safety; Energy; and International Trade & Commerce.
Through NEMA, member companies are able to develop and implement tailored, industry-specific market and statistical programs that benefit participating companies. Reports may include:
- Product orders and sales
- Market forecasting
- Shipments by trading areas
- Channels of distribution
- Financial and operating ratios
- Wages and benefits
- Foreign trade
The association also conducts economic analyses on the impact of legislation and regulations on member products, and monitors and reports on key industry market indicators. All programs comply with NEMA statistical confidentiality policies. For more information, please see Business & Economy.
Membership in NEMA is open to any firm actively engaged in the manufacture in North America of a product within the NEMA scope and for sale in the open market. Membership of foreign firms is subject to product section policies and NEMA Board of Governors approval.
NEMA operates on a fee-for-service basis. Each product section establishes its projects and activities and approves an annual operating budget. Visit Joining NEMA for more information on membership.
